You who have followed this blog notice that I do change my mind. For instance, I was a great supporter of the Five Tibetans – and to a degree, I still am. But then my lower back spoke up against the practice, and now I do modified exercises. I let you know.

Was my first opinion untrue? Not really. Different people have different needs, and plenty of people come back to me and tell me that I once recommended the Five Tibetans to them – and they are still doing them daily, and happily.

Spending time on the Internet and blogging about health sometimes feels to me as if I hit a wall: We health nuts are discussing minor improvements in our diets, when the majority of people are eating junk food, don’t know how to even cook rice (forget BROWN rice!), and spending every free minute in front of TV that carries them into fake worlds while stealing innumerable hours of their lives and their powers away.

That might apply to my blogs, too: Somebody reading this, is not walking right now, not playing an instrument, not gardening, not repairing a bike, not cooking stinging nettle greens, not making love, not painting the lilac in bloom now, not taking a cold shower.

And my blog (or all the other health blogs) doesn’t reach that majority. I have started worrying about this.

The other worry is that we bloggers seem to disperse truths – but we don’t seem to change minds. Or do we? I have been in too many online discussion where opinions about, say, homeopathy, clash, and the divides are never bridged.

We can say that most health improvements came at the beginning of the twentieth century with advancement of hygiene (better water supply, better sewage systems). Much less with antibiotics and vaccinations - as much as doctors want to exploit those tales. Then came our downfall in the fifties - the widespread automobile use let people walk less. And also in the fifties, housewives succumbed to advertisement that "helped" them spend less time in the kitchen: canned food, microwaves, ready-made dinners, take-out food, supplements, and what not. And in the seventies, HFCS, sealing our fates (or coffins).

So, this is my question of today? How do we make up our minds about what is healthy? Do we believe every published research study - some good, some shotty - or the myriad of business interests that pipe up on all occasions?

For me, after all the years of studying, health has become simple: Follow what Nature intended, and you will be all right. For all the little details: Hard to get at the truth. Besides, the truth might be manifold.
